Figure 13.
The stress-strain loops of the LVAD simulations at the third cycle (t = 1,500–2,250 ms) of stable 2,100 RPM pump speed (Left), speed increment to 3,150 RPM (Middle) at (t = 2,250–3,000 ms), and mitral stenosis (t = 1,500–2,250 ms) (Right). Sff is the 2nd Piola-Kirchoff stress and Eff is the Green-Lagrange strain tensor components along the fiber direction.
